Vacuum Metrology Inc - Model AVCS3SD -Stationary Automatic Vacuum Calibration System

The AVCS3SD Automated Vacuum Calibration System is designed for fast precision automatic, semiautomatic or manual calibration and verification of various vacuum gauges at pressures from 1.3x10-3 to 1.3x10+5 Pa (1x10-5 to 1000 Torr). The system provides calibration capabilities for Capacitance Manometers, Pirani, Piezo, Cold Cathode (Penning), Hot Cathode (Bayard-Alpert) and other types of gauges.

The system is compliant with the requirements of the ISO 3567:2011(E) standard, “Vacuum gauges – Calibration by direct comparison with a reference gauge”

The system incorporates 3 high-accuracy NIST or PTB traceable transfer standards with accuracy of up to ±0.025% (±zero and span), temperature regulated at 45°C; and fully automatic, patent pending, pressure and process control system, along with a Calibration Management Software.

Stainless Steel vacuum chamber incorporates 3 ports for the Transfer Standards and 3 Test Ports equipped with KF16 style flanges. All test and transfer standard ports incorporate automatic failsafe isolation valves. The two stage pumping system consists of a dry (scroll) backing pump and a Turbo molecular pump.

The system is built on a cleanroom compatible aluminum frame with all of the components mounted within the frame footprint. Frame has a built in casters and leveling pads.

AVCS automation consists of a PC running the GUI and process control and an Allen Bradley PLC responsible for operation of the vacuum hardware and pressure control loop.

AVCS offers a built in Calibration Management Software suite to ensure compliance with ISO 90XX, ISO/IEC 17025, ANSI Z540 and other industry specific quality standards.
